BUILDING GONSTEUCTION.

Specification of Letters Patent.

I latented March 23, 1909.

Application filed. MarchBO, 1908. Serial No. ceases To all whom it may concern:

,Be it known that 1, SMITH Torn, of the city of WVinnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Building Construction, of which the following is the specification.

My invention relates to im rovements in building construction, especia lyto the 'manner in which the joists are anchored to the walls of the building, and the objects of the invention are to provide a self releasing joist anchor which will be strong and inexpensive, which will bind the building together and prevent spreading, and which will further prevent the walls from'being torn down in event of displacement of the joist;

A further object is to provide an anchor for joist which will adjust itselfto the settling of the building, in this wise preventing breaking the bond of the material from which the wall is constructed.

The invention consists essentially in providing within a recess in the wall a stationary cross bar and in attaching to the joist to be anchored, a hooked bar adapted to hook over the cross bar when the joist is in position, the joist being cut at its end so that it will clear the recess when it is swung downwardly, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 represents a perspective view of a portion of a wall and a joist, the joist being held in position by means of my invention,

Fig. 2 is a vertical sectional view through the.

wall of a building, the section being taken through the recess and showing a joist in side elevation held in position by my bars.

Fig. 3 is a sectional view corresponding to Fig. 2, the sition.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 represents the usual masoned wall which is shown as being constructed from brick.

2 is a recess formed in the wall to receive the end of the joist 3 which rests with its under face 4 abutting-the brick work forming The recess is constructed in width so that it will receive the joist snugly and it extends within the wall a distance which will give su'liicient bearing for the end of the joist on the brick work, and also allow for the insertion of my joist being shown in a turned pobars, as explained. The end 5 of the joist entering the brick work is cut at an angle from the outer end of the joist to the inside of the wall leaving a vertical face at 6 for a-purpose shortly to be explained.

7 is a cross bar preferably made of steel or other such strong metal and it is inserted in the wall on its edge with its ends passing be ..t ween the rows of bricks thereby holding it permanently in position. The central portion of the bar passes across the recess with its lower edge resting on the brick work forming the lower face of the recess.

8 is a hooked bar fastened by bolts 9 or other such means firmly to the oist, and the hooked end 8 of the bar passes slightly beyond the squared end 6 of the joist. When the joist is placed in position the cross bar 7 is received tightly within the space, between the hooked end 8 of the bar and the squared end of the beam and in this Way the beam is prevented from longitudinal displacement.

The bricks forming the inner wall 10 of the recess are cut away so that in event of the beam being turned or thrown downwardly it will not engage with the wall, this being best shown in Figs. 2 and 3, where in Fig. 3 the hook'is disengaged from the cross bar.

In applying my hooked bar to a metallic joist the joist would necessarily need to be drilled for the reception of bolts and the bar could be shaped to accommodate existing be inserted the end having been previously cut at an angle, and the vertical face 6 would be placed against the cross bar. The hooked bar would then be placed over the cross bar and immediately spiked or bolted to the side of the oist. As soon as this had been done the remainder of the wall would be built up, the recess being left therein, the form of it being as already described.

it is well known that the joist anchors now in use are so permanently and solidly attached and fixed to the wall that if the joist were broken or destroyed by fire or other causes, the weight pressing on the broken,

burned, or weakened joist would cause the anchored end of the joist to breakaway from the Wall and consequently break the Wall,

thereby weakening the complete. structure and possibly causing a dangerous collapse. With my oist, in event of such circumstances as these, it Would free itself immediately from the Wall Without tearing or breaking and avoid any collapsing of the Walls and their consequent. dangers What I claimas my invention is:

In a device ot the classdescribed, the combination with the, Wall having a recess therein and a joist adapted to enter the recess, one

mp0s

corner of the joist being cut oil' at an angle so as to leave a short vertical face, 6, a cross bar set on edge and passing through the recess adjacent its inner face, and a bar secured to the joist" and having its end hooked, the hooked part passing beyond the end of the joist and forming with the face 6 a recess into which the cross ar fits.

Signed at W innipeg, in the Province of Manitoba, this 16th day of March 1908.
